Abstract:
Calpastatin is the specific inhibitor of the ubiquitous calcium-dependent proteases mu-calpain and m-calpain. Enzyme assay data from sheep and cattle inversely correlates post-mortem muscle calpastatin levels with ultimate meat tenderness. Genetic markers of meat quality may therefore be found linked to the calpastatin gene (CAST). A three-allele system detected by polymerase chain reaction-single strand conformational polymorphism (PCR-SSCP) has been observed in the ovine CAST. The three allele amplimers have been fully nucleotide sequenced and their differences in terms of single nucleotide polymorphism (SNPs) in the intron region of the amplimer are reported and compared to a consensus sequence of the orthologous region of the cattle CAST. A PCR-RFLP for more rapid CAST genotyping of all three ovine alleles was also developed.

Comparing Copy Number Variations and SNPs
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...
